We develop a new econometric framework that simultaneously allows recovering heterogeneity in demand, TFP and markups across firms while leaving the correlation among the three unrestricted. We do this by systematically exploiting assumptions that are implicit in previous firm-level productivity...

Observationally equivalent workers are paid higher wages in larger firms. This fact is often named as the "firm-size wage gap" and is regarded as a key empirical puzzle. Using micro-level data from Turkey, we document a new stylized fact: the firm-size wage gap is more pronounced for informal...

In this paper we provide an analysis of the process of creative destruction across 24 countries and 2-digit industries over the past decade. We rely on a newly assembled dataset that draws from different micro data sources (business registers, census, or representative enterprise surveys). The...

How and why does the firm size distribution differ across countries? Using two datasets covering more than 30 countries, this paper documents that several features of the firm size distribution are strongly associated with income per capita: the entrepreneurship rate and the fraction of small...

A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct frms, which...

Motivated by the fact that some regulations involve extra costs for those firms at a size beyond a critical threshold, this paper contributes to the analysis of the welfare distortions due to these regulations. In the context of a duopoly, our results show that social welfare is not monotonic...

This study examines serial correlation in employment, sales and innovative sales growth rates in a balanced panel of 3,300 Spanish firms over the years 2002-2009, obtained by matching different waves of the Spanish Encuesta sobre Innovacion en las Empresas, the Spanish innovation survey...

This study compares the employment growth patterns of innovative and non-innovative firms focusing on whether there are systematic differences in the persistence of the jobs created. Using data from a unique longitudinal dataset of 3,300 Spanish firms over the years 2002-2009, obtained by...

This paper advances understanding of the relationship between tax policy and productivity, taking advantage of unique data from the Dominican Republic to document a significant negative impact of tax regulations on total factor productivity (TFP). It begins by estimating productivity using...

The superstar firms model provides a compelling explanation for two simultaneously occurring phenomena: the rise of concentration in industries and the fall of labor shares. Our empirical analysis confirms two of the underlying assumptions of the model: the market share increases and the labor...
